Syntax
-
object.CoordToPolar Cx, Cy, Frequency, Phase, [Width], [Height]
The CoordToPolar Method syntax has these parts: |
| object | An expression evaluating to an object of type McFFT. | | Cx | Required. A Long value. X position of the complex element in the FFT data.
| | Cy | Required. A Long value. Y position of the complex element in the FFT data.
| | Frequency | Required. A Double value. double* : Output frequency.
| | Phase | Required. A Double value. double* : Output phase.
| | Width | Optional. A Long value. Optional width of the FFT data.
| | Height | Optional. A Long value. Optional height of the FFT data.
|
Remarks
Phase varies between 0 and 360 degrees. Frequency varies between 0 (DC component) and sqrt(2)/2 (Nyquist frequency). If either Width or Height is ignored its value is taken from the parent image which must be the resulting IMcImage of the Forward transform.
